According to the manual found at
https://www.manualslib.com/manual/88...02.html#manual it is dated 1993. BUT, it doesn't quite look like the 3343C
Personally, I don't think of any plastic machine as vintage. It seems like a lot of disagreement as to what "vintage" is. One place said " Most antique dealers consider an item to be vintage if it is at least 40 years old." Another said "Ruby Lane also suggests that ‘vintage’ should not be used in reference to objects less than 20 years old."

It does look like a decent mechanical machine. Sometimes people have serviced these machines with the wrong products that will cause parts to cement in place or crack the internal workings.
Other than that, I really can't help.
